Our report dated February 25, 2016, on the effectiveness of internal control over financial reporting as of December 31, 2015, contains an explanatory paragraph that states management chose to exclude from its assessment of the effectiveness of internal control over financial reporting, Marquette Financial Companies’ (Marquette) internal control over financial reporting, which was acquired on May 31, 2015. Marquette constituted approximately 6.1% of total assets for the year ended December 31, 2015. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of Marquette.
